Efficacy Study of a Selective Chest Wall Restriction Belt in Postoperative of Lung Resection (CTS-POP)

Efficacy Study of a Selective Chest Wall Restriction Belt in Postoperative of Lung Resection. A Multicenter, Prospective, Controlled, Randomized Study With Stratification on the Surgical Approach, Open With a Blind Analysis

The objective of this study is to evaluate the efficacy of a new medical device in post-surgery of lung resection. The principle of this new device is based on selective chest wall restriction. This new modality of chest wall restriction is evaluated on patients in post-surgery for lung cancer.

The hypothesis is that the use of this medical device would reduce the postoperative pain and increase the efficacy of cough and expectoration. The evolution of the operated patient would be better.

Study Overview

• Status: Recruiting
• Conditions: Lung Cancer
• Intervention / Treatment: Procedure: Conventional follow-up; Device: Conventional follow-up+chest wall restriction belt

Detailed Description

The present study is the first evaluation of the efficacy of a selective chest wall restriction belt.

The efficacy will be estimate on forced expiratory volume in one second (FEV1) at D3 by comparing 2 groups: a control group of patients with conventional follow-up and an experimental group of patients with conventional follow-up and a daily wear of the selective chest wall restriction belt after surgery.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Conventional follow-up+chest wall restriction belt; Patients in this group benefit from conventional post-operative follow-up and wear the selective chest wall restriction belt in parallel. Patients in this group benefit from conventional post-operative follow-up . From Day 1 to Month 1	Procedure: Conventional follow-up; Patients in this group benefit from conventional post-operative follow-up; Device: Conventional follow-up+chest wall restriction belt; Patients in this group benefit from conventional post-operative follow-up. The patient wear the selective chest wall restriction belt from Day 2 (after surgery) until he ceases to need it.
Active Comparator: conventional postoperative follow-up; Patients in this group benefit from conventional post-operative follow-up . From Day 1 to Month 1	Procedure: Conventional follow-up; Patients in this group benefit from conventional post-operative follow-up

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Comparison of forced expiratory volume in one second (FEV1) between the two groups.	Comparisons of forced expiratory volume in one second (FEV1) between the two groups at Day 3. The value of FEV1 is standardized with pre-operative one.	3 days

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Comparisons of pulmonary function test between the two groups	Comparisons of pulmonary function test ( forced expiratory volume in one second (FEV1), Forced vital capacity (FVC)) between the two groups. They are expressed as Liters. Before surgery, all days from Day 2 to the patient's exit from hospital (max Day 6) and at the follow-up visit at Month 1. Each value is standardized with pre-operative one.	1 month
Comparisons of Peak expiratory flow at cough between the two groups	Comparisons of Peak expiratory flow at cough (PEF) between the two groups. It is expressed as Liters per second. Before surgery, all days from Day 2 to Day 6 and at the follow-up visit at Month 1. Each value is standardized with pre-operative one.	1 month
Pain evaluation at rest and during cough: ENS scale	The patient pain is evaluated using the ENS (Echelle Numérique Standard; standard digital scale, score between 0 to 10) for the two groups.

The EQ-5D-5L consists of 6 items that cover 5 main domains (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) and a general visual analog scale (VAS) for health status. Each item has 5 response levels ranging from level 1 (no problem or none) to level 5 (unable to perform activity). The VAS ranges from 0 (worst health status) and 100 (best health status). Comparison between the two groups preoperatively, at the patient's exit from hospital, at Day 15 during the phone follow-up and at the follow-up visit at Month 1.	1 month

This questionnaire uses Likert scale from 0 to 10 to evaluate each use step of the medical device, closed-ended questions and open questions for comments. A descriptive analysis will done with the answers; Closed-ended questions will be asked in a questionnaire specifically created about acceptability and use of the medical device. A descriptive analysis will done with the answers and will be asked during the weekly phone follow-up.	1 month
